What is the flow rate in mL/hr for a 1500mL IV infusion over 12 hours?

To determine the flow rate in mL/hr for a 1500mL IV infusion to be completed in 12 hours, the calculation involves dividing the total volume of the infusion by the total time in hours.

Start by using the formula for flow rate:

Flow rate (mL/hr) = Total Volume (mL) / Total Time (hrs)

In this case, the total volume is 1500 mL, and the total time is 12 hours. Plugging these values into the formula gives:

Flow rate = 1500 mL / 12 hrs = 125 mL/hr

Thus, the correct answer is 125 mL/hr, indicating that in order to administer the entire 1500mL over the period of 12 hours, a constant flow rate of 125 mL/hr is required. This ensures that the infusion is delivered at a consistent pace, aligning with the prescribed treatment schedule.
